Brilliant - very interesting stuff. I had never dreamed that such detail would be available, having grown up with the idea that there were no rego records.
I have the typing machine, and can incorporate new info into the draft with ease, but I think you see the problem I am finding all the time: in a book outlining 550 or so Australian motorcycle brands, how much detail does one put in for each entry? By the time you start saying "two CCs arrived first, followed by a gap, then the rest..." and making it sound good, the word count grows quickly, but does the reader get that much more?
Being able to search the scanned newspapers is an extraordinary advantage over the old days. An Australia-wide search for "Cottman Colt" would likely show up repeated adverts in an interstate newspaper, so not finding anything much gives confidence to say that the Cottman Colt was not retailed actively interstate. Add to that a "feel" for the local industry. Cottman & Co were a Melbourne retail business, with bike and car agencies, who just wanted to sell more bikes than the guy next door - they weren't trying to take over the country with the Cottman Colt! Other cities around the country had their own equivalents - the Acmes, Waratahs, Utilities...
The thing I fear most is "losing" information. In this case in the draft I deliberately left out "stories" that could have been put in. For example that there were "several hundred" Cottman Colts, that the bikes were ordered from RE with modifications that were subsequently incorporated into the 1939 models. I'm sure these stories were told in good faith, but sometimes they don't quite stand up to scrutiny. If there were "hundreds" of CCs to get rid of, there would be big adverts and low prices (didn't happen), and of course the 1939 RE models were finalised about August 1938...
Anyway, we'll add the 65-ish bikes, the bulk of which arrived towards the end of 1939. Great stuff!
Thanks
